Estimate the electricity cost of operating an EV heat pump over a trip or recurring driving schedule. See traction energy, heat-pump energy, total charging energy after losses, and the climate system’s share of cost.
Adjust the inputs to compare your EV charging or energy scenario.
Grid energy = (distance × driving energy per mile + heat-pump power × trip hours) ÷ charging efficiency. Cost = grid energy × electricity rate.
This is a planning model; actual EV and charger performance can vary with temperature, equipment, and operating conditions.
The main result summarizes the modeled outcome from your inputs. Secondary results expose the energy, time, capacity, or cost components so you can identify which assumption drives the estimate.
For 60 miles at 0.29 kWh/mile, 1.4 kW for 1.5 hours, 90% charging efficiency, and $0.18/kWh, the trip costs about $3.90.
| Input | Unit | Example |
|---|---|---|
| Distance per trip | miles | 60 |
| Driving energy use | kWh/mile | 0.29 |
| Heat pump draw | kW | 1.4 |
| Trip duration | hours | 1.5 |
| Electricity rate | $/kWh | 0.18 |
| Charging efficiency | % | 90 |
| Trips per month | trips | 20 |
The energy, power, time, or utilization inputs that appear directly in the formula have the greatest effect. Change one input at a time to compare scenarios.
No. It is a planning estimate based only on the values you enter and does not connect to a vehicle, battery-management system, charger, or utility account.
Enter percentages as displayed numbers, such as 90 for 90%. The calculator converts them to decimal form internally.
Temperature, battery conditioning, charging curves, vehicle limits, tire condition, station sharing, fees, and driving conditions can change real-world results.
Yes. Calculate the first scenario, note the results, then change one or more inputs. The reset button restores the example defaults.
